Say it ain’t snow.

Even as gardeners were starting to clear the ground and bicyclists were pedaling to work, a slow-moving spring snowstorm blanketed coastal Maine with a layer of wet snow Wednesday, creating near-blizzard conditions in some areas and treacherous roads that resulted in a spate of accidents throughout Hancock and Washington counties.

State police stopped traffic on Route 9 in Wesley and evacuated homes within a half-mile of a cargo tanker crash Wednesday afternoon, fearing that combustible methanol might be leaking from the tank.

Trooper Micah Perkins said the truck, driven by David Crane, 32, of Auburn, was headed east up Day Hill on Route 9 about 1 p.m. in a spring snowstorm. Crane pulled around a log truck, which was stuck at the roadside, and into the oncoming lane, just as a Wesley plow truck driven by Glen Durling, 37, of Wesley came over the hill. Durling struck Crane’s truck, doing $10,000 damage to each vehicle. State police blamed road conditions for the crash and no summons was issued.

DEP officials determined there was no leakage and no injuries were reported, Perkins said.

In Ellsworth, two people suffered minor injuries when a pickup truck collided with a fuel delivery truck on the Surry Road. According to Officer Troy Bires of the Ellsworth Police Department, Marjorie Hall, 31, of Stonington was traveling south toward Blue Hill on Route 172 when she lost control of her vehicle on the slippery road.

Her pickup swerved into the northbound lane toward an Emerson Oil delivery truck driven by Bruce Trahan, 56, of Ellsworth. Trahan tried to avoid the oncoming vehicle, but the passenger side of Hall’s pickup struck the oil truck. The pickup left the road, flipped onto its roof and came to rest on a lawn. The oil truck also left the roadway, coming to rest in a clump of trees.

A rescue crew from the Ellsworth Fire Department removed Hall from her pickup. She was taken to Maine Coast Memorial Hospital, treated and released. Trahan complained of back pain after the accident but did not seek treatment. The impact of the collision cracked the gas tank on the oil truck. About 30 gallons of diesel fuel leaked onto the ground. Ellsworth firefighters were on the scene to clean up the spill.

Hall’s pickup, a 1988 Chevrolet, had an estimated $4,000 in damage and was considered a total loss. Bires said the delivery truck, a 1999 International, had extensive damage.

In Mount Desert, a vehicle collided with a town plow truck, sending one man to the hospital.

According to Police Chief Merrill Naylor, Anthony Waite of North Hampden was traveling on slippery Sargent Drive when he lost control of his vehicle. Waite’s car skidded into the path of a town plow truck and struck the truck head-on, Naylor said.

Waite’s injuries included a possible broken clavicle. He was taken to Mount Desert Island Hospital for treatment. The driver of the plow truck, whose name was not available, was not injured.

Waite’s vehicle, a 1990 Nissan, was considered a total loss. There was little damage to the plow truck.

Police officers in both counties were kept busy throughout the afternoon, with the Washington County Sheriff’s Department reporting an estimated 30 accidents during the height of the storm. The storm also forced officials at Acadia National Park to close all the roads into the park.

The storm was caused by a low-pressure system that stalled over the western tip of Nova Scotia and joined forces with with a batch of cold air from the northwest, according to Mark Bloomer, a meteorologist with the National Weather Service in Caribou.

“They came together to form a rather thin storm line with a heavy band of snow that extended from northern Hancock County northeast across Down East Maine,” he said.

The snow had ended in Hancock County by early evening but continued to fall, heavily in some places, in Washington County, where most of the accumulation occurred. Some areas Down East received as much as 6 inches in the storm.
